I worked several decades in the Aerospace business. Did some commercial stuff (Boeing, Airbus, etc.), but worked mainly on military jets and other military goodies. Main focus was wingtip fabrication (shit was done by hand forming, little tooling). Damn tolerances were +.003 -.002 on many items. Commercial was +/- .010 usually. Worked on B1, F117, F22, F15, F16, F18, SR71 etc.. Started during the Reagan era and retired a while back. But the company I worked for always set up at the Dayton Air Show and we always got free tickets. Was always hot as hell there, but loads of fun !!! I have a B52 map reading light I will take pics of and post sometime. Pretty cool little light. Fuckers were pricey !! That military mark up !! One year we went to the show and the Harriers kept overheating during their hover maneuvers. It was like 101 in the shade that day !! Fun times. I have not been in a few years. If they have it this year I will definitely go and take grandkids. But if you ever get a chance to go to an airshow do so !!!
